2 Claims. (01. 215-42) This invention relates to closures for nonrefillable bottles or other containers, and it has for its object to provide an improved closure that will allow the free passage of the contents therefrom but will prevent refillingafter the contents of the container is exhausted,

Another object of the invention is to provide a closure for non-refillable bottles or other containers, that can be easily and expeditiously secured to the bottle or container, which cannot be removed therefrom without breaking or .damaging the means permanently securing the closure to the bottle or container.

A further object of the invention is to provide a. closure for non-refillable bottles or containers, that will guarantee the genuineness of the contents thereof and retain same free from contamination until completely exhausted, which is neat and simple in construction, inexpensive to manufacture by reason of the minimum of the elements composing same, and perfectly efficient in operation.

This invention will be described with reference to the figures of the accompanying drawings, of which:

Fig. 1 is a diametral vertical section view of the closure applied to a bottle neck in upright position.

Fig. 2 is a view similar to Fig. 1, showing the bottle neck inverted for pouring the contents therefrom and through the closure.

Fig. 3 is a sectional view taken on the line AA of Fig. 1.

Fig. 4 is a top plan View of the loose valve operating within the closure.

Fig. 5 is an elevation of the valve. 7

Fig. '6 is an elevation of the disc which forms a seat for the semi-spherical lower portion of the valve.

Fig. 71s a dimetral sectional view of the closure applied to a bottle neck in horizontal position.

In the drawings, the numeral l indicates the neck of a bottle wherein there is inserted a hollow cylindrical body 2 which may be formed from glass or a plastic material and which has its lower end open and provided with inner threads 3 and its upper end 4 closed and of a diameter slightly greater than that of the lower open end. Said'upper end 4 is provided at its outer surface about its line of greater diameter with relation to the rest of the body 2, with an annular flange 5 upon which is disposed an apertured rubber washer 6 upon which is fitted a metallic cap 22 which permanently secures the closure to the bottle neck and beneath said annular flange 5 there is provided another annula apertured washer I through which said annular flange 5 seats upon the mouth or upper end of the bottle. Said upper end 4 has at the middle portion of its outer side surface a flattened area having centrally arranged thereon an opening 8 and an exteriorly threaded nipple adapted to. act as an outlet for the contents of the bottle.

Said hollow cylindrical body 2 is tapered from opening 8 to a point near its lower open end'and. has formed at a certain height of its inner wall inter-spaced tooth-shaped projections 9 adapted to serve as stops for a pellet In which is prefersably formed from glass or metal or an alcohol-a proof material. Said pellet I0 is loosely disposed between said projections 9 and the top portion of a valve H which is loosely inserted within the lower threaded end of cylindrical body 2. On the innerly threaded lower open end of body 2 there is screwed an innerly conical disc 12 which is reduced in half of its lower surface and has contrally formed on its upper surface an outerly threaded nipple 21 having its upper edge burnished to a semi-spherical contour said nipple 2| being adapted to act as a seat for the valve H.

The lower open end of body 2 has formed in its inner wall and near its edge an annular recess [4 having formed therewith four inter-spaced tooth-shaped projections l5 and above said annular recess [.4 there are suitably formed four other inter-spaced tooth-spaced projections IB, allsaid projections serving to guide the valve II in its movement within the lower open end of body 2.

The closed end 4 of body 2 has formed in its side opposite the liquid outlet opening 8 an air inlet opening 13 extending vertically within the wall of body 2 and ending in the annular re cess I4.

The valve ll consists of a burnished cylindrical member having its top portion open and its bottom portion closed in. a semi-spherical shape having centrally formed therein a hole and arranged thereon an outer nipple 11, said valve having laterally formed therein two opposed square openings I9, Within the semi-spherical end of valve ll there is disposed at piece'of cork Or other floatable material l8 whose upper edge reaches near the upper edges of openings I9 the cork or other floatable material being recessed at its edges, such recesses or slots coinciding with said upper ends of openings I9, so that liquid may flow through the openings l9. into the inte rior oi the valve body II. as will be more specifis sally pointed out and described hereinafter.

In the top open end of valve I I there is pressure fitted a rectangular member 20 which is adapted to serve as a stop for the cork piece I8 and also as a seat for the pellet I0, said rectangular member 20 having a small perforation at the middle portion of its upper surface.

The closure of this invention is secured to the neck of the container by means of an annular metallic cap 22 having centrally formed in its upper plane surface an opening through which protrudes upwardly the upper end of body 2, the

side edges of said cap being of a suitable length so that pressure on said side edges will cause same to be tight against and beneath the outer flange of the bottle neck I. v

The operation of this closure is as follows:

' ings and with an annular recess interiorly of its When it is desired to pour the contents of the j container, it is tilted from its: upright position to the position shown in Fig. 2. When so arranged the air entering through air inlet I3 will allow the contents to pass freely through the central opening of the disc I2 into the annular recess l4 through the spaces provided by the projections I5, whereupon the liquid will displace the valve I I onward at the same time that the pellet I0 drops on the projections 9. The liquid then flows through the opposed lateral square apertures I9 of the valve I I and through the two openings into which the upper open end of the valve I I is divided by the rectangular piece fitted therein, and the liquid also flows in a smaller amount through the spaces provided between the projections I6. Finally the liquid passes through the spaces between the projections 9 and the remaining portion of the body 2, to find its way out through the discharge outlet 8 It is evident that an attempt to inject liquid into the bottle through outlet nipple 8 of the closure in the normal or upright position of the bottle will be futile, by reasonof the fact that the valve II, with the aid of the weight of pellet Ill which normally rests on the top portion of the valve, will normally rest on the burnished edge of the nipple of disc I2 wherethrough the liquid to be poured enters into the closure, and the pressure exerted by the liquid being injected into the closure will force the valve I I on its seat and the pellet I0 upon the valve, whereupon the liquid upon being prevented from passing down into the bottle will tend to find its way out through air inlet'opening'l3. "Similarly, liquid cannot be injected into the closure in the horizontal'position of the bottle as shown in Fig. '7, due to the fact that by reason of the conical shape of the inner wall of the body 2, the pellet Ill normally tends to run to its resting position on the valve I I and to force the valve I I on its seat formed 'on the disc I2 wherethrough the liquid to be discharged flows into the closure, whereupon the liquid will be prevented from flowinginto the bottle and will find its way out through the'a ir inlet opening I3.

' If an attempt should be made to force liquid into the closure in the tilted position of the bottle shown in Fig. 2, the valve, due tothe floating nature of the cork enclosed therein,'will ascend as the liquid enters into the closure, until it fits against the disc I2 which normally acts as the valve seat, whereby the liquid will be prevented from entering into the bottle and compelled to find its way out through air inlet opening I3.

It is evident that in any position of the bottle, if an attempt should be made to inject liquid into the closure by obturating either the air inlet or the liquid discharge openings, the very pressure lower end, a metallic cap that inviolably secures said hollow cylindrical body to the upper end of the container through a washer, a cylindrical valve loosely disposed within said hollow cylindrical body and slidable therein, and which is open above and closed below and ends in a semispherical portion having centrally arranged therein and formed therewith an outer nipple, a portion of a fioatable material disposed within said semi-spherical portion of the valve, guiding means for said valve in its movement within said hollow cylindrical body, a seat for said valve, a pellet loosely disposed within said hollow cylindrical body and adapted to normally rest on the top of said valve, and means for limiting the run of said pellet within said hollow cylindrical body.
